I'm not sure if you want comments, or just posting because or what, but I see a few things that won't work.

You should use 1 ESC module with the output going to both ECMs. Alternatively, you will need 2 knock sensors if you want to use the 2 ESC modules.

You can't connect both ECMs to the IAC motor. You'll have to let one of them control it.

Your IGN relay is wrong, the pink should be on the right terminal.

You'll need a coolant temp sensor for each ECM.

I believe the TPS and MAP can be shared but I'm not sure you want to connect the sensor 5V terminals together. I think you'll want to use the 5V from one ECM for the TPS and MAP with the common and outputs going to both ECMs.

I highly doubt you can run closed loop which makes the O2 sensors rather pointless. The control loops get out of sync and the one ECM will be adding fuel via one injector while the other is trying to remove it via the other injector causing a big fuel imbalance.
